Gatsby Icarus Theme Starter

Gatsby Icarus Theme Starter is a Gatsby v3 blog starter that recreates the Icarus theme from Hexo, letting you build a static blog like Kun's Blog from markdown content. It is open source, hosted on GitHub under the Kun8018/gatsby-starter-icarus-blog repository, and is designed to deploy to Netlify with one click.

What is Gatsby Icarus Theme Starter?

Gatsby Icarus Theme Starter is a Gatsby v3 starter that builds a static blog website with an Icarus-like theme (from Hexo) and markdown-based content management. It takes markdown files from the src/content directory as input and produces a fully functioning static blog with pagination, tags, and comments, ready to deploy to Netlify or GitHub Pages. The starter is maintained by Kun8018 and is available as an open-source GitHub repository.

Key Features

• Gatsby v3 engine — uses GatsbyJS v3 for faster builds, offline support via service workers, and a Web App Manifest for installability.
• Google Analytics — built-in integration; you add your tracking ID in the configuration file to start collecting site analytics.
• Gitalk comment component — comments are powered by Gitalk, a GitHub issue–based commenting system, configured with client ID, client secret, repository, and owner details.
• SEO and sitemap — includes search engine optimization and automatic sitemap generation for better indexing.
• Pagination and tags — posts are organized with page pagination and can be grouped under different tags.
• Responsive design — the layout is fully responsive and styled with SCSS, closely resembling the Icarus theme from Hexo.
• Markdown content authoring — write posts as Markdown in src/content, or edit them through the built-in Netlify CMS support.
• TypeScript support — the starter supports TypeScript for developers who prefer typed JavaScript.

Who is it for?

• Bloggers who want a modern Gatsby-based blog with a clean, card-style layout similar to Hexo's Icarus theme.
• Developers who want a ready-made starter with SEO, offline support, and comment integration so they can focus on writing content.
• Netlify users who want one-click deployment through the Netlify Deploy button, which automatically creates a GitHub repository and publishes the site.
• Hexo users looking to migrate to Gatsby while keeping an Icarus-like look and feel.

Use cases

• Personal blog: publish technical or personal articles as Markdown files and get a static site with tags, pagination, and analytics.
• Documentation or notes site: use the markdown pipeline and sitemap to create a lightweight documentation hub.
• Comment-enabled writing: enable Gitalk comments so readers can discuss posts via GitHub issues without building a custom backend.

How does it work?

1. Click the "Deploy to Netlify" button, authenticate with GitHub, and choose a repository name — Netlify creates a copy of the starter, builds it, and deploys the site.
2. To develop locally, install the Gatsby CLI, run gatsby new new-blog https://github.com/Kun8018/gatsby-starter-icarus-blog, then npm install and npm start to launch a hot-reloading dev server at http://localhost:8000.
3. Customize the blog by editing the config object in the data/config file — including blog title, meta description, theme color, favicon, social links, and the Gitalk plugin settings.
